IMPROVEMENT IN ADVERTISING MEDIUMS.

Specification forming part of Letters Patent No. 165,147, dated July 6, 1875; application filed March 19, 1875.

To all whom it may concern:

Be it known that I, HORACE BALDWIN, of the city and county of Philadelphia, State of Pennsylvania, haveinvented a new and Improved Advertising Medium; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, in which- Figure 1 is a view showin g'the top and three sides of my improved advertising medium complete. Fig. 2 is a perspective view, and Fig. 3 an enlarged cross-section of Fig. 1.

The object of my invention is to provide an advertising medium which shall, in use, present to the eyea variety of advertisements. At the same time it may be used for a weight to retain papers in a'fixed position upon a table, and which, from its inexpensive construction, can be readily put upon sale at a small cost.

Fig. 2 of the drawings shows a plain glass vessel, A, of hexagonal form, or having six sides, aswat b tapering from the bottom to the mouth of the vessel, as shown, thus forming six independent interior columns .or spaces, within which paper cards with advertisements printed thereon may be exposed, as indicated in Figs. 1 and 3. These cards b, after having been cut to fill each space I), as indicated in Fig. 1, are treated with a strong cement or gum spread upon their printed or face sides, after which the gummed side of each is placed against the respective columns or spaces b, so as to expose the advertisement printed upon them, as indicated in Fig. l. A like card out in hexagonal form, as at b Fig. l, and made to fit the interior surface of the bottom b of the vessel, is also gummed and applied to such bottom, so as to expose an advertisement thereon through the glass bottom, as indicated in said figure. This being done the vessel is then filled with plaster-paris'in a plastic state, which sets and dries along with the paste or cement upon the cards.

After the vessel is filled, or nearly so, with the plastic plaster-paris, another card cut in proper form to fit the mouth of vessel is placed upon the plasteraris at a point a little below the mouth or top of the vessel, with the blank face of the card gummed and placed upon the plaster-paris, which, with the plaster-paris, holds the lastnamed advertisin g-card securely in place. Thus, on all sides and at both ends the cards are made to screen from view theinclosed massof plaster-paris within the vessel, while at the same time, on all the sides and at each end of the vessel A, advertisements are exposed to the eye.

Thus constructed I produce an advertising medium cheaply made, and possessing, when used as a paper weight, the requisite weight to retain papers -in place upon a table, and while thus used presenting manifold advertisements to the eye of the observer.

In applying the plaster-paris inside of the vessel, room is left between the lower end of 1. A glass vessel, A, having spaces there-- in, in combination with advertising-cards b applied with their printed faces against such spaces, substantially as and for the purpose described.

2. A glass vessel having advertising-cards held in place against its interior by filling the vessel with plaster-paris, substantially as described.
